% Length and Angle L = sqrt((x2-x1)^2 + (y2-y1)^2); c = (x2-x1)/L; s = (y2-y1)/L; % Solve the system u = K\F; This

K_global(idx, idx) = K_global(idx, idx) + ke; F_global(idx) = F_global(idx) + fe; end c = (x2-x1)/L

The workhorse of plane stress/strain analysis. The CST is the simplest 2D element, and mastering its M-file unlocks complex geometries.

% Gauss quadrature points and weights (4-point for quadrilateral) gauss_points = [-1/sqrt(3), 1/sqrt(3)]; gauss_weights = [1, 1];
